please answer with explain ​

Answer 1

Answer:

It is given that O is the centre of a circle and ∠BOD =150°

We know that

Reflex ∠BOD = (360° – ∠BOD)

By substituting the values

Reflex ∠BOD = (360° – 150°)

By subtraction

Reflex ∠BOD = 210°

Consider x = ½ (reflex ∠BOD)

By substituting the value

x = 210/2

So we get

x = 105°

We know that

x + y = 180°

By substituting the values

105° + y = 180°

On further calculation

y = 180° – 105°

By subtraction

y = 75°

Therefore, the value of x is 105° and y is 75°.
